Abstract：In this paper a new type of low-viscosity modified asphalt is introduced, which is produced by adding viscosity reducer to asphalt. The mechanism of viscosity reducer action on the asphalt performance is studied. According to the results of both lab tests and experimental road, the low-viscosity modified asphalt is verified to be a well-working pavement material.
